Degreasing with Corn Cobs


Recently we have negotiated an order for supply of Battery Components. These require degreasing and deburring using Corn Cobs. The product size id 12.00 mm Diamater. Could somebody guide us on the process and the source of procuring Corn Cobs? Normally we are using Abrasive media and these would be the first time with Corn Cobs.

Thanking you in anticipation.

Corn Cob is a common product in great abundance here in the USA. It comes in a number of screen sizes. There are at least 4 common sizes that are available and we stock, but special screen sizes can be purchased in volume. The weight of untreated cob runs around 22 to 33 pounds per cubic foot, that is about 1/4 the weight of ceramic materials. Because it is organic material, you better check export regulations or restrictions, so cost of product may have to include fumigating. I hope this helps.

Dear Mr Naresh,

The name used for corn cobs here is " naar " or even fibre. This may include the dried coconut shell also along with the corn. People have used even sawdust with heating over the deburring chamber with good results. I personally prefer silicon carbide for consistency and availability.
